d6c01556f1 tap-vsockd: add buffering 
This patch adds a simple ring buffer implementation and uses it to buffer
the reads and writes to/from the AF_HYPERV socket and tap file descriptor.

This removes the need to perform small reads and writes for the per-packet
headers and allows a read on the Hyper-V socket to block at the same time
as a write to the tap device (and vice-versa)

The configuration in the init.d script is:

- a max message size (individual read or write) of 8192. Experimentally
  this seems to be the largest completely reliable size across the Windows
  versions we can support. Messages of length 16384 sometimes fail.
- a buffer size of 256KiB in each direction.

Single stream TCP throughput as measured by iperf increases modestly, by
another 100Mbit/sec.

d308fdac11 Fix up direct database accesses after move to /Database 
In #1057 removed the 9p paths from the database mount
but that broke some users accessing them directly. Fix these.

fc72448ffd kernel: Add VMBus stability improvements 
The four new patches prevent swamping VMBus with too many
notifications which, eventually, let Hyper-V assume there is
a DoS attempt and would thus throttle the VM for up to 5s.

The first three new patches were cherry-picked from upstream.
The final patch was received by email. Will update once it
has been submitted/accepted upstream.

These never got an interface on any platform, and I don't think they
ever will, we can increase global limits or you can set something
with a privileged container. Can add back later if required.

Use a bind mount for OSX and Windows for 9p filesystem.

This makes it easier to use a different database source,
and to share database into system containers.

In most places we use the Alpine one, which is already here, but
make sure this is updated, as we may use it more (yes, we should be
consistent).

Change the hash to just use the ca-cert hash, not the apt hash.
